Cleaning encrypted USB drives
Cleaning encrypted USB drives
Hey everyone. I'm looking at some outdated USB drives—4GB USB 2.0 models called IronKey Enterprise. I want to reuse them instead of throwing them away, especially since my team still lacks portable storage options and we’d rather not force anyone to purchase new devices. The software is tied to our company, so I need a valid corporate email and activation code. No one has the codes yet, and my attempts to wipe or format have failed consistently. I've used tools like DiskPart, CCleaner, Xcinerate, and Parted Magic, but all returned errors or warnings that the drive can't be wiped. Parted Magic was my final option because it offers various wiping methods, including random numbers and all zeros. The IronKey.exe remains on the USB, and the context menu doesn’t let me delete it, while Properties doesn’t provide a format path. Any advice or alternatives would be greatly appreciated.
If the drives use SSD technology, you can erase them using strong neodymium magnets.
They need to use 4GB USB 2.0 storage without encryption. You can reset the partition table, make fresh partitions, and format it. I experienced an SSD failure because of self-encryption, but Samsung handled it with a warranty.
Use sudo blockdev to set a writeable block on the correct device. If that fails, check with lsblk—hardware locks may be in place. There might be a small microcontroller on the USB; proprietary software could trigger it to unlock once everything is ready. Ideally, the flash should behave like regular flash, but bypassing security might require soldering if you're dealing with a 4GB drive. Consider buying multiple smaller drives instead.
This concept came from SSD-based storage being very resistant to magnets.
It seems these devices include a built-in encryption chip... These units were designed to prevent any unauthorized access to this information.
